Throughout
this
document,
the
terms
"
State"
or
"
States"
are
used
to
refer
to
all
types
of
primacy
agencies.
There
are
currently
57
primacy
entities,
including
the
50
States,
the
District
of
Columbia,
U.

territories
(
Puerto
Rico,
U.

Virgin
Islands,
Guam,
American
Samoa,
and
Northern

and
the
Navajo
Nation.
Though
Wyoming
and
the
District
of
Columbia
do
not
have
primacy,
the
EPA
burden
for
these
activities
counts
as
primacy
agency
burden.

Characterization
The
Office
of
Ground
Water
and
Drinking
Water
(
OGWDW)
in
the
Office
of
Water
at
the
United
States
Environmental
Protection
Agency
(
EPA
or
the
Agency)
is
responsible
for
managing
the
Public
Water
System
Supervision
(
PWSS)
Program,
a
national
program
mandated
by
the
Safe
Drinking
Water
Act
(
SDWA).
Section
1412
of
the
SDWA
requires
EPA
to
establish
National
Primary
Drinking
Water
Regulations
(
NPDWRs)
for
contaminants
that
may
adversely
impact
human
health.
The
Act
further
requires
EPA
to
monitor
and
enforce
these
regulations
to
ensure
that
the
nation's
drinking
water
dependably
complies
with
the
maximum
contaminant
levels
(
MCLs)
or
maximum
residual
disinfectant
levels
(
MRDLs),
as
stipulated
in
the
Code
of
Federal
Regulations
(
CFR),
40
CFR
Part
141,
Subpart
B.

Section
1445
of
the
SDWA
stipulates
that
every
drinking
water
supplier
must
conduct
monitoring,
maintain
records,
and
provide
such
information
as
is
needed
for
EPA
to
implement
its
monitoring
and
enforcement
responsibilities
with
respect
to
the
Act.
State1
governments
 
in
those
States
that
have
assumed
primary
enforcement
responsibility
(
i.
e.,
primacy)
for
public
water
systems
(
PWSs)
under
the
SDWA
Section
1413
 
ensure
that
PWSs
are
complying
with
these
monitoring
requirements.
As
part
of
the
PWSS
Program,
the
OGWDW
uses
the
Safe
Drinking
Water
Information
System
(
SDWIS)
2
to
record
some
of
the
data
collected
as
a
result
of
NPDWR
requirements.
SDWIS
is
a
database
management
system
that
assists
EPA
in
tracking
and
interpreting
monitoring
data
and
other
program­
related
data.
These
data
assist
EPA
in
fulfilling
its
SDWA
obligations.

are
addressed
in
this

as
monitoring
for
UCMR

associated
with
the
SDWA
and
its
implementing
regulations
are
associated
with
rulemakings
that
address
specific
contaminants
or
groups
of
contaminants.
This
ICR
examines
PWS,
primacy

of
annual
burden
between
PWSs
and
primacy
agencies
is
approximately
4.3
million
hours
and
2.1
million
hours,
respectively.
The

This
section
identifies
the
regulatory

authority
for
the
information
collection
activities
covered
in
this
ICR
and
explains
EPA's
need

ICR
contains
a
summary
of
the
major
types
of

and
reporting
requirements
for
chemical
contaminants
covered
by
this
ICR.

To
allow
the
public
to
better
understand
the
impact
of
the
recordkeeping
and
reporting
requirements
stemming
from
the
SDWA
and
40
CFR
Parts
141
and
142,
OGWDW
has
organized
its
ICRs
so
that
related
activities
are
addressed
in
the
same
ICR.
Specifically,
there
are
three
primary
ICRs
 
the
Microbial
Rules
ICR,
the
Disinfectants/
Disinfection
Byproducts,
Chemical
and
Radionuclides
Rules
(
DDBP/
Chem/
Rads
Rules)
ICR,
and
the
Public
Water
Systems
Supervision
Program
(
PWSS
Program)
ICR.
The
Microbial
Rules
ICR
includes
rules
addressing
microbial
contaminants,
such
as
the
Total
Coliform
Rule
(
TCR),
Surface
Water
Treatment
Rule
(
SWTR),
and
the
Filter
Backwash
Recycling
Rule
(
FBRR).
The
PWSS
Program
ICR
includes
public
notification
and
rules
addressing
cross­
cutting
requirements
that
are
not
associated
with
contaminant­
specific
rule.
The
DDBP/
Chem/

ICR
includes
rules
addressing
chemical
contaminants.
The
specific
chemical

As
EPA
publishes
new
regulations,
EPA
will
amend
the
appropriate
ICR
to
include
the
new
rules.

For
a
graphical
depiction
of
the
structure
of
the
OGWDW
ICRs,
see
Figure

A
complete
itemization
of
the
activities
included
in
the
three
primary
ICRs,
as
well
as
other
drinking
water
program
ICRs,
is
included
as
Exhibit
1.

The
1986
Amendments
to
the
SDWA
require
the
Agency
to
publish
maximum
contaminant
level
goals
(
MCLGs)
and
promulgate
NPDWRs
for
83
specific
contaminants.
Promulgation
of
the
chemical­
related
rules
contained
in
this
ICR
complies
with
the
statutory
requirements
for
some
of
these
contaminants.
Promulgation
of
the
Stage
1
DBPR
complies
with
the
amended
statutory
requirements
for
these
contaminants.

In
addition,
the
1986
SDWA
Amendments
require
the
EPA
to
propose
and
promulgate
a
NPDWR
specifying
criteria
under
which
filtration
would
be
required
as
a
treatment
technique
for
public
water
systems
supplied
by
surface
water
sources
(
Section
1412
(
b)(
7)(
C)(
i)).
Promulgation
of
the
SWTR
satisfied
this
SDWA
requirement.

The
information
collected
under
this
ICR
is
required
by
EPA
to
carry
out
its
monitoring
and
enforcement
responsibilities
under
SDWA.
Without
comprehensive,
up­
to­
date
information
on
chemical
contaminants
present
in
drinking
water,
the
Agency
would
not
be
able
to
meet
the
SDWA
statutory
requirements.

Section
1401
of
the
SDWA
requires
that
 
there
must
be
criteria
and
standards
to
assure
a
supply
of
drinking
water
which
dependably
complies
with
such
maximum
contaminant
levels;
including
quality
control
and
testing
procedures
to
insure
compliance
with
such
levels
and
to
insure
proper
operation
and
maintenance
of
the
system...

Further,
§
1445
of
the
SDWA
requires
that
 
every
person
who
is
a
supplier
of
water
shall
establish
and
maintain
such
records,
make
such
reports,
conduct
such
monitoring,
and
provide
such
information
as
the
Administrator
may
reasonably
require
by
regulation
to
assist
him
in
establishing
regulations,
in
determining
whether
such
person
has
acted
or
is
in
compliance
with
this
title...

In
addition,
§

of
the

1986
Amendments
defines
NPDWRs
to
include
"
criteria
and

which
dependably
complies
with
such

This
section
authorizes
EPA
to
require
systems
and
laboratories
to
use
Agencyapproved
methods
and
quality
assurance
criteria
for
collecting
and
analyzing
water
samples.

Vulnerability
Assessments
and
Emergency
Response
Plans
for
CWSs
To
implement
its
compliance
oversight
and
enforcement
responsibilities
under
the
SDWA,
EPA
requires
PWSs
to
monitor
for
various
drinking
water
contaminants.
The
results
of
this
monitoring
must
be
reported
to
primacy
agencies,
which
in
turn
report
a
specified
subset
of
this
information
in
SDWIS.
Additionally,
both
PWSs
and
primacy
agencies
must
maintain
records
of
analytic
results
and
other
related
activities
(
e.
g.,
sanitary
survey
results).
Without
comprehensive,
up­
to­
date
information
on
drinking
water
contamination
(
as
provided
by
SDWIS),
EPA
would
not
be
able
to
ensure
a
supply
of
drinking
water
which
dependably
complies
with
such
maximum
contaminant
levels.
If
these
monitoring
requirements
were
voluntary,
EPA
would
not
receive

timely,
comprehensive
data
on
contaminant
levels
and
associated
acute
and
long­
term
public
health
risks.
Specifically,
voluntary
monitoring
would
not
 

Reliably
occur
with
sufficient
frequency.


Follow
uniform
national
standards
on
quality
of
sampling,
collection,
and
analysis.


Ensure
that
monitoring
addresses
all
contaminants
listed
in
the
regulations.

Thus,
without
this
information
collection,
EPA
would
not
be
able
to
guarantee
safe
drinking
water
for
the
nation.

Additionally,
EPA
uses
SDWIS
data
to
estimate
the
costs
of
new
regulations
and
to
conduct
economic
and
policy
analyses
that
promote
cost­
effective
regulatory
approaches.
These
uses
are
discussed
in
more
detail
in
Section
2(
b)
below.

Section
4
of
the
ICR
contains
a
summary
of
the
major
types
of
chemical
contaminant
recordkeeping
and
reporting
requirements,
as
mandated
by
40
CFR
Parts
141
and
142.
Specifically,
most
reporting
required
by
PWSs
can
be
found
in
§
§
141.31,
141.34,
and
141.35.
Most
recordkeeping
requirements
for
PWSs
are
codified
in
§
141.33,
which
requires
that
the
results
of
chemical
analyses
be
kept
for
a
period
of
at
least
10
years.
Reporting
and
recordkeeping
required
by
States
can
be
found
in
§
§
142.15
and
142.14,
respectively.

are
EPA
Headquarters,
PWS
managers,
and
primacy
agencies,
which
include
State

and,
in
some
instances,
EPA
Regional

are
used
specifically
for
analytical

analyses,
and
other
Agency
and
public

and
use
these
data
to
 

Evaluate
the
quality
of

Alert
the
public,
through
notices
in
the
mass
media
or
water
bills,
when
the
system
is
not
in
compliance
with
Federal
and
State
regulations
so
that
they
may
take
actions
to
minimize
exposure
to
potentially
harmful
drinking
water
contaminants.

Quarterly
and
annual
reports
that
primacy
agencies
must
submit
to
EPA
include
analytical
results,
by
contaminant
type,
for
each
PWS.
This
reporting
is
required
to
establish
primacy
and
maintain
eligibility
for
grants.
All
of
this
information
is
stored
in
SDWIS,
which
supports
overall
maintenance
and
retrieval
of
information.
SDWIS
contains
information
on
the
following:
inorganic
chemicals,
organic
chemicals,
radionuclides,
microbiological
contaminants,
and
turbidity.
Thus,
SDWIS
allows
EPA
to
compare
water
system­
level
compliance
data
from
year
to
year
and
to
analyze
compliance
trends
at
the
system,
State,
and
national
program
levels.

Regulatory
Enforcement
Using
SDWIS,
system­
level
compliance
data
may
be
compared
from
year
to
year
and
trends
in
compliance
data
can
be
evaluated
at
the
system,
State,
and
national
program
levels.
Primacy
agencies
are
responsible
for
enforcement
activities
and
can
use
SDWIS
data
to
track
compliance
progress
in
their
jurisdictions,
to
identify
enforcement
targets
and
systems
requiring
remedial
action,
and
to
monitor
progress
of
capacity
development
strategies.
The
primacy
agency
must
also
track
enforcement
actions
issued
against
each
PWS
not
in
compliance
with
drinking
water
standards
and
evaluate
the
system's
status
in
meeting
schedules
designed
to
return
the
PWS
to
compliance.

On
a
quarterly
basis,
EPA
uses
SDWIS
to
generate
a
list
of
PWSs
that
are
in
significant
non­
compliance
(
SNC).
EPA
can
use
these
data
to
oversee
State
programs
and
support
Federal
enforcement
actions
in
cases
where
States
fail
to
enforce
against
violations
of
drinking
water
standards.
If
a
State
has
failed
to
take
timely
and
appropriate
action,
EPA
may
become
directly
involved
in
enforcement
by
issuing
an
administrative
order.
If
the
system
does
not
comply
with
the
order,
EPA
may
seek
an
administrative
penalty
or
court
action.
EPA
may
also
take
action
against
a
PWS
before
it
is
in
SNC.

Another
output
of
SDWIS
evaluations
is
an
annual
compliance
report
prepared
jointly
by
OGWDW
and
the
Office
of
Enforcement
and
Compliance
Assurance
(
OECA),
which
provides
a
national
perspective
on
contaminant­
by­
contaminant
trends
in
compliance.
This
report
allows
OGWDW
managers
to
examine
important
policy
questions
relating
to
enforcement.
For
example,
managers
may
use
this
information
to
determine
if
current
regulations
and
implementing
policies
are
producing
intended
results.
If
not,
they
may
then
identify
the
types
of
changes
needed
to
meet
program
objectives.

Oversight
of
State
Programs
State
reporting
is
a
condition
for
maintaining
primacy.
Primacy
agencies
play
a
crucial
role
in
implementing
the
SDWA,
and
EPA
is
charged
with
overseeing
the
performance
of
these
States.
Generally,
EPA
Regional
Offices
perform
this
duty
and
use
SDWIS
data
to
develop
summary
statistics
on
individual
State
performance.

In
addition,
EPA
uses
the
data
to
evaluate
the
impact
of
SDWA
requirements
on
primacy
agencies.
The
data
allow
EPA
to
gauge
if
it
has
accurately
estimated
the
impact
of
the
SDWA
on
States
implementing
and
enforcing
the
various
drinking
water
regulations.
Such
data
provide
EPA
with
the
opportunity
to
improve
program
effectiveness
and
efficiency
and
identify
areas
requiring
additional
focus.
Specifically,
EPA
uses
the
Resource
Analysis
Computer
Program
for
State
Drinking
Water
Agencies
to
support
this
State
impact
evaluation.
The
model
contains
a
comprehensive
list
of
activities
required
to
operate
a
drinking
water
program.

Implementation
Assistance
EPA
also
uses
the
data
collected
to
assist
small
systems
in
implementing
SDWA
requirements,
including
developing
variances
and
exemptions
and
evaluating
PWS
capacity.
If
a
PWS
is
unable
to
meet
standard
requirements
due
to
source
water
quality
or
affordability
concerns,
a
variance
or
exemption
would
allow
the
system
to
comply
with
slightly
different
drinking
water
standards
or
implementation
schedules
that
are
still
protective
of
public
health.
Capacity
development
is
a
State
effort
to
help
all
drinking
water
systems,
particularly
small
systems,
improve
their
finances,
management,
infrastructure,
and
operations.
This
helps
ensure
that
safe
drinking
water
is
provided,
consistently,
reliably,
and
cost­
effectively.

Economic
and
Policy
Analyses
SDWIS
data
are
used
extensively
in
developing
Economic
Analyses
(
EAs)
of
proposed
new
regulations
or
revisions
of
existing
regulations.
The
data
help
to
determine
a
system's
susceptibility
and
vulnerability
to
contaminants,
as
well
as
the
potential
for
co­
occurrence
of
contaminants.
Data
are
also
used
by
OGWDW
to
conduct
analyses
used
in
developing
new
policies,
regulations,
and
guidance
documents.
When
analyzing
economic
or
financial
impacts
on
the
water
supply
industry
or
consumers,
EPA
uses
compliance
data
from
SDWIS,
together
with
other
national
survey
data,
to
estimate
the
number
of
systems
that
would
have
to
install
treatment
technologies
or
apply
contamination
reduction
measures
to
reduce
public
health
risks.
Without
such
data,
EPA
would
be
unable
to
predict
costs
and
benefits
that
systems
would
incur
under
new
or
revised
regulations.

Additionally,
EPA
uses
such
data
to
revise
characterizations
of
public
health
and
environmental
risks.
This
information
is
then
used
to
determine
if
less
stringent
regulation
is
warranted.
For
example,
EPA
will
use
the
unregulated
contaminant
monitoring
data
to
formulate

regulations.
Specifically,
the
data
generated
by
the
UCMR
1
will
be
used
to
evaluate
and
prioritize
contaminants
on
the
Drinking
Water
Contaminant
Candidate
List
(
CCL),
a
list
of
contaminants
EPA
is
considering
for
possible
new
drinking
water
standards.
These
data
will
help
to
ensure
that
future
decisions
about
drinking
water
standards
are
based
on
sound
science.

EPA
solicited
public
comment
on
this
ICR
for
a
60­

Consultations
As
a
standard
regulatory

Before
any
rule
is
finalized,
EPA
logs
and
evaluates
all
written
comments
on
proposed
rules.
Additionally,
EPA
usually
holds
public
meetings
during
which
any
interested
party
may
provide
oral
testimony
for
Agency
consideration.
Such
meetings
are
typically
announced
in

In
developing
the
final
version
of
the
1991
LCR,
EPA
consulted
with
NDWAC
and
requested
comments
from
its
Science
Advisory
Board.
The
monitoring
requirements
of
the
LCR
reflect
comments
made
by
the
drinking
water
industry.
In
addition,
during
the
comment
period
for
the
1991
LCR,
approximately
28,000
comments
were
received
from
approximately
3,000
individuals
and
organizations.
Most
recently,
EPA
developed
the
Lead
and
Copper
Rule
Minor
Revisions
(
LCRMR)
(
promulgated
in
January
2000)
and
held
the
following
meetings,
consultations,
and
work
group
discussions
to
address
these
modifications:

S
The
LCRMR
workgroup
(
comprised
of
EPA
Headquarters
and
Regional
staff
as
well
as
State
drinking
water
officials)
was
established
in
1993
and
held
several
discussions
throughout
development
of
the
LCRMR.

S
Several
EPA­
sponsored
stakeholder
meetings
were
held
to
discuss
burden
reduction
efforts
and
development
of
the
LCRMR.

S
OGWDW
'
s
Data
Sharing
Committee
worked
with
several
States
and
ASDWA
to
revise
primacy
agency
reporting
requirements
based
on
comments
received
on
the
April
1996
proposed
changes.

In
1998,
prior
to
publishing
additional
notices
for
comment,
EPA
provided
national,
local,
and
tribal
organizations
with
brief
articles
for
inclusion
in
their
newsletters.
These
articles
announced
EPA's
plans
to
publish
the
notices
and
encouraged
readers
to
provide
comment
on
the
additional
regulatory
options,
which
would
be
described
in
those
notices.

S
EPA
coordinated
closely
with
States
and
several
national
organizations
to
provide
copies
of
the
August
18,
1998,
notice
directly
to
water
systems
most
likely
to
be
affected
by
the
regulatory
options
discussed
in
the
notice.
This
included
all
water
systems
serving
more
than
50,000
people
and
any
smaller
water
system
likely
to
continue
to
exceed
an
action
level
after
the
installation
of
corrosion
control
treatment.

S
EPA
distributed
a
draft
of
the
proposed
modifications
to
ASDWA
and
major
water
utility
trade
associations.
These
groups,
in
turn,
circulated
the
draft
to
their
members
and
requested
written
comment.

S
Written
comments
were
received
from
numerous
Regional
offices
and
State
agencies.

S
PWS
input
was
gathered
through
State
comments,
as
well
as
comments
submitted
by
AMWA
and
AWWA.

S
During
February
1999,
EPA
consulted
with
a
State
Unfunded
Mandates
Reform
Act
panel
regarding
the
revised
ICR
burden
and
cost
estimates
for
the
LCR
and
LCRMR
and
assumptions
used
to
derive
these
estimates.

S
Many
of
the
suggestions
received
through
written
comments,
at
Stakeholder
meetings,
from
work
group
discussions,
and
through
other
consultations
were
incorporated
into
the
final
rule.

Since
the
regulations
covered
by
this
ICR
are
not
new,
the
typical
consultations,
workshops,
and
meetings
were
not
held
immediately
prior
to
the
development
of
this
document.

Effects
of
Less
Frequent
Collection
EPA
has
considered
a
wide
range
of
alternatives
for
frequency
of
data
collection.
EPA
has
chosen
to
require
the
least
frequent
collection
that
remains
consistent
with
the
overall
goal
of
protecting
public
health.
If
data
are
collected
less
frequently,
primacy
agencies
may
not
identify
in
a
timely
fashion
significant
contaminant
concentrations
that
might
threaten
the
health
and
safety
of
drinking
water
consumers.

SMF
was
originally
promulgated
under
the
Phase
II
Rule
and
revised
under
Phase
IIB
and
Phase
V
regulations
(
CFR
§
§
141.23­
141.25).
It
standardizes
monitoring
requirements
within
chemical
contaminant
groups
and
synchronizes
monitoring
schedules
across
chemical
contaminant
groups
into
specific
three­
year
compliance
periods
and
nine­
year
compliance
cycles.

18
For
some
rules,
the
primacy
agency
has
discretion
in
adjusting
monitoring
schedules,
where
possible
(
e.
g.
by
granting
waivers).
Monitoring
frequencies
have
been
carefully
devised
based
on
the
following
 

Type
of
contaminant.


Type
and
size
of
system.


System
vulnerability.


Contaminant
history.


Factors
contributing
to
DBP
formation
(
Stage
1
DBPR
only).

Similarly,
UCMR
1
monitoring
frequencies
were
determined
based
on
statutory
requirements,
which
specify
that
monitoring
be
varied
based
on
the
number
of
people
served
by
a
system,
contaminants
likely
to
be
found,
and
source
of
supply.
The
monitoring
frequency
design
also
considers
that
the
number
of
people
served
affects
exposure
to
contaminants,
as
well
as
the
resources
available
to
undertake
monitoring
activity.
Monitoring
frequencies
have
been
carefully
devised
based
on
the
following
factors
 

Data
quality
needed
for
a
representative
sample.


Precision
and
accuracy
needed
from
the
representative
sample.


Number
of
people
served
by
the
system.


Source
of
the
supply
(
e.
g.,
surface
water
or
ground
water).


Contaminants
likely
to
be
found.


Temporal
variability
in
occurrence.


Synchronization
with
the
Standardized
Monitoring
Framework
(
SMF)
for
Phases
II/

For
the
UCMR
1,
reduced
data
collection
would
seriously
affect
the
integrity
of
the
data
and
result
in
insufficient
data
to
fulfill
the
needs
envisioned
by
the
1996
SDWA
Amendments.
These
data
will
be
used
for
continued
development
of
the
CCL,
support
of
the
Administrator's
regulatory
determinations,
and
overall
regulation
development.

switches
between
the
use
of
chlorine
and
chloramines,
compliance
must
be
determined
by
including
all
monitoring
results
for
both
chlorine
and
chloramines
in
calculating
compliance.


Reporting
and
Recordkeeping
Requirements
(
§

Chlorine
Dioxide
MRDL
Chlorine
dioxide
is
used
primarily
for
the
oxidation
of

odor­
causing
organic
compounds
in

It
can
also
be
used
for
the
oxidation
of
iron,
manganese,
and
color
and
is
a
powerful
disinfectant
and
algicide.
Chlorine
dioxide
reacts
with
impurities
in
water
rapidly
and
is
dissipated
quickly.
About
60
to
70
percent
of
the
chlorine
dioxide
is
converted
to
chlorite
in
the
treatment
process.
This
provision
applies
to
CWSs,

141.134).
Systems
must
report
the
dates,
results,
and
locations
of
samples
taken
during
the
previous
quarter;
whether
the
MRDL
was
violated;
whether
the
MRDL
was
exceeded
in
any
two
consecutive
daily
samples;
and
whether
the
resulting
violation
was
acute
or
nonacute.

DBP
PRECURSORS
Subpart
H
systems
employing
conventional
filtration
must
monitor
for
TOC
and
alkalinity
in
their
source
and
finished
water.
These
samples
determine
treatment
technique
requirements.


Routine
Monitoring
(
§
141.132).
Systems
must
take
one
paired
sample
per
month
of
the
TOC
in
source
water
(
at
a
point
prior
to
treatment)
and
treated
water
(
at
a
point
no
later
than
the
combined
filter
effluent
turbidity
monitoring).
These
samples
must
be
taken
simultaneously.
Additionally,
systems
must
take
one
alkalinity
sample
per
month
at
the
same
time
as
the
source
water
TOC
sample.


Reduced
Monitoring
(
§
141.132).
Systems
may
take
one
paired
sample
per
quarter
if
their
average
treated
water
TOC
is
less
than
2.0
mg/
L
for
two
consecutive
years
or
less
than
1.0
mg/
L
for
one
year.
The
alkalinity
sample
is
taken
at
the
same
time.
If
the
average
treated
water
TOC
in
these
systems
is
>
2.0
mg/
L,
they
must
revert
to
routine
monitoring.


Compliance
Requirements
(
§
141.133).
Compliance
is
determined
by
the
requirements
of
§
141.135(
c).
This

Reporting
and
Recordkeeping
Requirements
(
§
141.134).
Systems
must
report
various
monitoring
and
compliance
results
depending
on
their
TOC
removal
requirements,
how
frequently
they
have
to
monitor,
and
whether
or
not
they
have
met
the
alternative
compliance
criteria
described
in
§
141.135.

MONITORING
PLANS
Under
the
Stage
1
DBPR,
each
system
required
to
conduct
monitoring
must
develop
and
implement
a
monitoring
plan
(
§
141.132).
The
plan
must
describe
 

The
locations
and
schedules
for
collecting
the
required
samples.


How
the
system
will
calculate
its
compliance
with
the
MCLs,
MRDLs,
and
treatment
techniques.


How
the
plan
reflects
the
entire
distribution
system.

The
system
must
maintain
its
plan
and
make
it
available
to
the
public
and
State
30
days
following
the
applicable
compliance
date.
Subpart
H
systems
serving
over
3,300
people
must
submit
their
monitoring
plans
to
the
State.
This
is
another
reporting
requirement
for
some
PWSs.
The
State
may
require
changes
in
any
element
of
the
system's
monitoring
plan.

2)
Chemical
Phase
Rules
The
chemical
monitoring
requirements
apply
to
CWSs
and
NTNCWSs,
although
transient
noncommunity
water
systems
(
TNCWSs)
must
also
sample
for
nitrate
and
nitrite.
Monitoring
requirements
follow
the
SMF
schedule
established
by
the
rule.
Under
the
SMF,
nine­
year
compliance
cycles
were
established;
the
first
cycle
lasted
from
January
1,
1993
to
December
31,
2001.
The
second
cycle
began
on
January
1,
2002,
and
ends
on
December
31,
2010.
Each
nineyear
cycle
consists
of
three,
three­
year
compliance
periods
(
e.
g.,
from
January
1,
2002,
to
December
31,
2004;
from
January
1,
2005,
to
December

INORGANIC
COMPOUNDS
This
section
summarizes
the
IOC
monitoring
requirements
for
the
second
three­
year
compliance
period
of
the
second
compliance
cycle
(
beginning
on
January
1,
2005),
as
described
in
40
CFR
141.23(
c).
For
the
purposes
of
monitoring
requirements,
the
IOCs
regulated
under
Phases
II
and
IIB
are
asbestos,
barium,
cadmium,
chromium,
fluoride,
mercury,
nitrite,
nitrate,
and
selenium.
The
IOCs
regulated
by
Phase
V
are
antimony,
beryllium,
cyanide,
and
thallium.
The
MCL
and
MCLG
for
nickel,
which
was
initially
included
as
part
of
Phase
V,
were
remanded
on
February
9,
1995.
This
means
that,
while
many
water
suppliers
continue
to
monitor
nickel
levels
in
their
water,
there
is
currently
no
EPA
legal
limit
on
the
amount
of
nickel
in
drinking
water.
Arsenic
was
regulated
under
the
1976
standards
for
IOCs
but
is
now
addressed
separately
in
the
Arsenic
Rule.

During
each
3­
year
compliance
period,
ground
water
systems
must
take
one
sample
at
each
sampling
point.
Surface
water
systems
must
take
one
sample
annually
at
each
sampling
point.
If
results
from
any
sampling
events
are
above
the
MCL,
the
PWS
must
begin
quarterly
sampling
during
the
next
calendar
quarter.
The
PWS
must
continue
quarterly
sampling
until
the
State
determines
that
the
samples
are
reliably
and
consistently
below
the
MCL
based
on
at
least
two
consecutive
quarterly
samples
for
ground
water
systems
and
four
consecutive
quarters
for
surface
water
systems.
Once
the
samples
are
reliably
and
consistently
below
the
MCL,
ground
water
systems
are
then
required
to
sample
triennially,
and
surface
water
systems
must
sample
annually.

After
three
consecutive
sampling
rounds
without
detection,
a
PWS
may
apply
to
the
State
for
a
waiver.
Should
the
State
grant
a
waiver,
the
PWS
is
required
to
sample
only
once
every
nine
years.
IOC
waivers
must
be
renewed
every
nine
years.
Waivers
are
not
available
for
nitrate
or
nitrite
monitoring.

VOLATILE
ORGANIC
COMPOUNDS
This
section
summarizes
VOC
monitoring
requirements
for
the
second
three­
year
compliance
period
of
the
second
compliance
cycle
(
beginning
January
1,
2005),
as
described
in
40
CFR
141.24(
f).

For
VOCs,
surface
water
systems
must
take
one
sample
annually
at
each
sampling
point.
During
each
three­
year
compliance
period,
ground
water
systems
must
take
one
sample
at
each
sampling
point.
If
any
sample
exceeds
the
method
detection
limit
(
MDL)
of
0.0005
mg/
l,
the
PWS
must
begin
quarterly
monitoring
during
the
next
calendar
quarter.
Quarterly
sampling
must
continue
until
the
State
determines
that
the
samples
are
reliably
and
consistently
below
the
MCL
based
on
at
least
two
consecutive
quarterly
samples
for
ground
water
systems
and
four
consecutive
quarters
for
surface
water
systems.
However,
if
the
detection
that
triggered
the
increased
sampling
exceeds
the
MCL,
the
PWS
must
take
a
minimum
of
four
consecutive
quarterly
samples,
regardless
of
whether
it
is
served
by
ground
water
or
surface
water.
Once
the
samples
are

the
State
may
reduce
the

frequency
to
once
per
year,
provided
repeat
sampling
is
conducted
during
the
calendar
quarter
that
previously
yielded
the
highest
analytical
result.

Systems
may
apply
to
the
State
for
a
waiver
after
three
years
of
annual
sampling
without
a
VOC
detection.
The
maximum
waiver
period
for
ground
water
sampling
points
is
six
years.
The
initial
waiver
must
be
renewed
within
the
first
three
years
of
issuance,
but
subsequent
waivers
may
be
renewed
at
the
end
of
the
six­
year
period.
A
ground
water
system
must
collect
one
sample
within
the
first
compliance
period
and
at
least
one
sample
during
each
six­
year
waiver
period.
For
surface
water
systems,
the
maximum
waiver
period
is
three
years,
but
there
is
no
minimum

frequency.
The
State
determines
the
sampling
schedule
for
surface
water
systems
with
a
three­
year
waiver.

SYNTHETIC
ORGANIC
COMPOUNDS
This
section
summarizes
the
SOC
monitoring
requirements
for
the
second
three­
year
compliance
period
of
the
second
compliance
cycle
(
beginning
January
1,
2005),
as
described
in
40
CFR
141.24(
h).

Systems
serving
more
than
3,300
people
are
required
to
take
two
SOC
samples
every
three
years.
For
systems
that
serve
fewer
than
3,300
people,
one
sample
is
required
every
three
years.
If
a
contaminant
is
detected
at
any
sampling
point,
the
water
system
must
begin
quarterly
sampling
during
the
next
calendar
quarter.
Quarterly
sampling
must
continue
until
the
State
determines
that
the
samples
are
reliably
and
consistently
below
the
MCL
based
on
at
least
two
consecutive
quarterly
samples
for
ground
water
systems
and
four
consecutive
quarters
for
surface
water
systems.
However,
if
the
detection
that
triggered
the
increased
sampling
exceeds
the
MCL,
then
the
PWS
must
take
a
minimum
of
four
consecutive
quarterly
samples,
regardless
of
whether
it
is
served
by
ground
water
or
surface
water.
Once
the
samples
are
reliably
and
consistently
below
the
MCL,
the
State
may
reduce
the
sampling
frequency
to
once
per
year,
provided
repeat
sampling
is
conducted
during
the
calendar
quarter
that
previously
yielded
the
highest
analytical
result.

After
three
years
of
annual
monitoring
without
SOC
detections,
systems
may
apply
for
a
waiver.
Waivers
are
effective
for
one
compliance
period
(
i.
e.,
three
years).
They
must
be
renewed
in
each
subsequent
compliance
period,
or
the
system
must
return
to
the
sampling
frequency
specified
for
its
size.
Under
Federal
regulations,
systems
with
a
waiver
are
not
required
to
sample.

Unregulated
Contaminant
Monitoring
Rule,
Lists
1
and
2
The
SDWA,
as
amended
in
1996,
requires
the
Agency
to
develop
an
Unregulated
Contaminant
Monitoring
Regulation.
The
requirements
for
unregulated
contaminant
monitoring
were
first
established
by
the
1986
Amendments
to
the
SDWA
and
were
included
as
part
of
the
Phase
I
chemical
regulation
under
40
CFR
Parts
141.40(
a)­(
e).
The
Phase
II
regulation
supercedes
the
Phase
I
rule.

Section
1445(
a)
of
the
SDWA
1996
Amendments
substantially
revises
unregulated
contaminant
monitoring.
The
new
program
includes:

1)
A
new
list
of
contaminants
(
i.
e.,
the
UCMR
List,
developed
in
coordination
with
the
CCL
process);
2)
A
representative
sample
of
PWSs
serving
10,000
or
fewer
people;
3)
Placement
of
the
monitoring
data
in
the
National
Contaminant
Occurrence
Database
(
NCOD),
authorized
under
the
SDWA
Amendments
§
1445(
g);
and
4)
Consumer
notification
regarding
of
the
availability
of
monitoring
results.

The
1996
Amendments
limit
the
number
of
contaminants
that
can
be
on
the
UCMR
List
to
30
or
fewer,
require
that
only
a
representative
number
of
systems
serving
a
population
of
10,000
or
fewer
people
be
required
to
monitor,
and
require
that
EPA
pay
reasonable
sample
analysis
costs
for
this
representative
sample
of
systems.

1976
Radionuclides
Rule
and
2000
Radionuclides
Rule
As
the
2000
Radionuclides
Rule
ICR
indicates,
in
1976
EPA
promulgated
National
Interim
Primary
Drinking
Water
Regulations
(
NIPDWRs)
for
three
categories
of
radionuclides:
gross
alpha
particle
activity,
combined
radium­
226
and
radium­
228,
and
gross
beta
particle
and
photon
radioactivity.
The
1976
NIPDWRs
for
these
radionuclides
regulated
 

Gross
alpha
at
15
picoCuries
per
liter
(
pCi/
L)(
excluding
radon
and
uranium).


Radium­
226
and
radium­
228
combined
at
5
pCi/
L.


Beta/
photon
emitters
at
a
4
millirem
(
mrem)
dose
of
radioactivity.

The
1986
SDWA
amendments
identified
83
contaminants
for
the
Agency
to
regulate,
including
the
currently
regulated
radionuclides
that
lacked
MCLGs,
and
two
additional
radionuclides,
uranium
and
radon.
Also,
the
1986
amendments
declared
the
1976
interim
standards
to
be
NPDWRs.

On
December
7,
2000,
EPA
promulgated
a
revised
radionuclides
regulation.
The
new
rule
completely
supercedes
the
requirements
established
in
the
original
1976
Rule.
The
2000
Radionuclides
Rule,
which
is
applicable
only
to
CWSs,
revised
and
amended
40
CFR
Parts
141
and
142
and
 

Sets
an
MCLG
of
zero
for
all
radionuclides.


Maintains
the
1976
gross
alpha
MCL
of
15
pCi/
L
(
which
includes
combined
radium­
226/­
228
and
excludes
uranium
and
radon).


Maintains
the
1976
MCL
of
5
pCi/
L
for
combined
radium­
226
and
radium­
228.


Maintains
the
1976
beta
particle
and
photon
radioactivity
MCL
of
4
mrem/
year.


Sets
an
MCL
of
30

g/
L
for
uranium.


Establishes
separate
monitoring
requirements
for
radium­
226
and
radium­

Maintains
the
beta/
photon
screening
levels
set
in
the
1976
Rule
for
vulnerable
systems
(
as
deemed
by
the
State).
Surface
water
systems
serving
greater
than
100,000
persons
will
no
longer
be
required
to
monitor
unless
they
are
deemed
vulnerable.


Revises
sampling,

points
to
the
distribution
system.
States
will
have
discretion
in
grandfathering
existing
distribution
system
data
for
determining
initial
monitoring
baselines.

5)
Total
Trihalomethanes
Rule
The
initial
1979
TTHM
standard
applied
only
to
surface
water
and
ground
water
CWSs
that
serve
at
least
10,000
people
and
that
add
a
disinfectant
to
the
drinking
water
during
any
part
of
the
treatment
process.
At
their
discretion,
States
could
choose
to
extend
coverage
to
smaller
PWSs;
however,
most
States
did
not
exercise
this
option.
Monitoring
requirements
are
detailed
in
40
CFR
141.30.

The
Stage
1
DBPR
lowers
the
MCL
for
TTHM,
the
only
group
of
DBPs
regulated
previously.
Specifically,
the
MCL
of
0.10
mg/
L
is
now
0.080
mg/
L.
As
a
result,
after
December
31,
2001,
§
141.64
superseded
§
141.12,
to
reflect
this
change.
Also
beginning
on
January
1,
2004,
the
Stage
1
DBPR
extends
the
requirements
to
systems
serving

Arsenic
Rule
As
stated
in
the
2001
Arsenic
Rule
ICR,
the
1986
SDWA
amendments
required
EPA
to
propose
new
arsenic
standards
by
January
1,
2000,
and
to
promulgate
the
rule
by
January
1,
2001.
The
rule
was
promulgated
January
22,
2001
and
requires
that
CWSs
and
NTNCWSs
follow
the
SMF.
As
previously
described
for
the
Chemical
Phases
Rule,
the
SMF
is
conducted
within
the
schedule
of
a
nine­
year
compliance
cycle.
The
compliance
cycle
is
subsequently
composed
of
three,
three­
year
periods.

Triggered
Monitoring
Surface
water
systems
will
have
until
December
31,
2006,
to
complete
initial
monitoring,
and
groundwater
systems
will
have
until
December
31,
2007,
to
complete
the
initial
monitoring.
NTNCWSs
are
required
to
follow
that
same
monitoring
regimen
as
CWSs.

For
existing

some
of
these
requirements
may
not
fall
within
the
collection

for
this
ICR
Amendment.
See
Appendix
H
for
detail
related
to

54
Routine
Monitoring
Groundwater
systems
must
take
a
sample
at
each
sampling
point
once
every
three
years;
surface
water
systems
must
take
a
sample
at
each
sampling
point
annually.
Triggered
monitoring
as
a
result
of
a
violation
requires
the
system
to
monitor
quarterly
beginning
in
the
next
quarter
after
the
violation
has
occurred.
Only
after
a
system
has
taken
two
consecutive
groundwater
samples
or
four
consecutive
surface
water
samples
and
the
State
has
determined
that
the
system
is
"
reliably
and
consistently"
below
the
MCL
(
40
CFR
141.23(
c)(
8))
may
the
system
return
to
routine
monitoring.

The
revised
requirements
also
allow
systems
to
receive
nine­
year
monitoring
waivers.
During
the
waiver
period,
a
system
must
take
a
minimum
of
one
sample.
In
order
to
receive
a
waiver,
a
system
must
demonstrate
that
during
the
previous
three
rounds
of
monitoring
all
results
were
less
than
the
current
MCL
and
there
was
adequate
source
protection.
In
the
initial
compliance
period
following
promulgation
of
the
revised
rule,
many
States
may
not
have
sufficient
historic
data
to
grant
waivers.
Before
granting
waivers
a
State
must
wait
until
three
years
of
monitoring
have
occurred
at
a
level
of
detection
sensitive
enough
to
monitor
for
the
current
MCL.

As
part
of
its

EPA
maintains
SDWIS
and
evaluates
SDWIS

to
determine
system

EPA
personnel
also
reformat,
distribute,
and
store
these

for
a
number
of
uses,
including
responding
to
Congressional

EPA
also
oversees
the
EPA
Regional
and
State
programs,
provides
technical

and
develops
policies
designed
to
ensure
consistent
program

EPA
officials
serve
as
respondents
when
testifying
to
Congress
on
the
PWSS
Program
or
in
the

for
enforcement
actions.

EPA's
requirements
are
outlined
in

primacy
agencies
must
report

to
EPA,
including
new
data
and
any
revisions
or
corrections
to
existing

is
maintained
in

Primacy
agencies
transmit
SDWIS

to
EPA
both
manually
and
electronically.
In
the
District
of
Columbia,
Wyoming,
and
Indian
Lands
(
except
for
the
Navajo
Nation,
which
has
primacy),
results
of
system

are
sent
directly
to
the
EPA
Region.
Virtually
all
SDWIS
data
are
reported
electronically
by
the
primacy
agency.
The
UCMR
requires
systems
to
report
some
data
in
addition
to
that
currently
required
by
§
141.35
and
requires
that
all
data
are
submitted
in
electronic

UCMR
allows
laboratories
to
report

directly
to
EPA,
but
clarifies
that
systems
are
ultimately
responsible
for
timely
reporting.

SDWIS

Small
Entity
Flexibility
In
developing
chemical
monitoring
rules
contained
in
this
ICR,
EPA
considered
the
requirement
of
the
Small
Business
Regulatory
Enforcement
Fairness
Act
(
SBREFA)
to
minimize
the
burden
of
information
collections
on
small
entities.
Small
entities
include
"
small
businesses,"
"
small
organizations"
and
"
small
government
jurisdictions."
These
terms
are
defined
below.
18

A
small
business
is
any
business
that
is
independently
owned
and
operated
and
not
dominant
in
its
field,
as
defined
by
the
Small
Business
Administration
regulations
under
Section
3
of
the
Small
Business
Act.


A
small
organization
is
any
non­
profit
enterprise
that
is
independently
owned
and
operated
and
not
dominant
in
its
field.


A
small
governmental
jurisdiction
is
the
government
of
a
city,
county,
town,
township,
village,
school
district,
or
special
district
that
has
a
population
of
fewer
than
50,000.
This
definition
may
also
include
Indian
Tribes.

The
major
requirement
under
SBREFA
is
a
regulatory
flexibility
analysis
of
all
rules
that
have
a
"
significant
economic
impact
on
a
substantial
number
of
small
entities."
This
ICR
is
not
associated
with
new
rules.
Therefore,
this
ICR
is
not
subject
to
the
SBREFA.
When
the
initial
Stage
1
DBPR
ICR
was
prepared
for
the
initial
implementation
phase
of
the
rule,
EPA
completed
an
RFA
because
it
had
determined
that
the
rule
would
have
a
significant
impact
on
small
systems.

However,
EPA
has
made
significant
efforts
to
minimize
the
burden
for
all
respondents,
particularly
for
small
entities.
In
setting
both
MCLs/
MRDLs
and
monitoring
requirements,
EPA
has
been
able
to
minimize
burden
for
small
entities
in
the
following
ways
 
1)
Stage
1
Disinfectants
and
Disinfection
Byproducts
Rule
EPA
has
taken
steps
to
minimize
the
burden
on
small
PWSs.
These
measures
include
lower
monitoring
frequency
for
small
systems,
reducing
monitoring
frequency
for
systems
consistently
and
reliably
below
the
MCLs
and
MRDLs,
and
extending
the
compliance
date
for
small
systems
to
five
years
after
promulgation
of
the
rule.

2)
Chemical
Phase
Rules
For
the
contaminants
regulated
under
the
Phase
II
regulation,
the
provisions
established
in
the
SMF
are
intended
to
minimize
burden
on
small
entities
by
allowing
systems
to
composite
as
many
as
five
samples
and
by
allowing
States
to
grant
waivers,
which
reduce
or
eliminate
monitoring
requirements.

For
Phase
V
chemicals,
EPA
has
taken
steps
to
minimize
the
burden
on
PWSs
(
in
addition
to
the
provisions
listed
for
Phase
II
contaminants)
by
allowing
systems
serving
fewer
than
3,300
people
to
composite
among
different
systems
provided
the
five
sample
limit
is
maintained.
Sample
collection
has
also
been
simplified
by
allowing
the
same
sampling
locations
to
be
used
for
all
source
water­
related
monitoring.

3)
Unregulated
Contaminant
Monitoring
Rule
1,
Lists
1
and
2
EPA
has
estimated
the
impact
of
the
UCMR
1
and
concluded
that
the
impact
on
small
water
systems
will
not
be
significant.
The
rationale
for
this
conclusion
is
that
EPA
plans
to
pay
the
full
costs
of
shipping
and
testing
samples
for
small
systems
and
does
not
plan,
under
any
scenario,
to
ask
systems
to
pay
these
costs.
Thus,
the
costs
to
these
systems
will
be
limited
to
the
labor
hours
associated
with
collecting
a
sample
and
preparing
it
for
shipping.
System
costs
under
both
a
"
Full
Assessment
Monitoring
Implementation"
and
"
Limited
Assessment
Monitoring
Implementation"
scenario
were
estimated
to
ensure
that
small
systems
would
not
incur
significant
economic
impacts
under
any
circumstances.

Rule
The
monitoring
requirements
for

apply
only
to

and
specify
different
monitoring
frequencies
depending
on
the
type
of
source
water.
Ground
water
systems
have
less
stringent
monitoring
requirements
and
since
most
small
systems
use
ground
water,
the
rule
imposes
less
burden
on
such
systems.
Specifically,
ground
water
systems
must
sample
at
least
once
every
four
years,
while
surface
water
systems
must
take
four
consecutive
quarterly
samples
once
every
four

the
TTHM
Rule
did
not
apply
to
small
PWSs,
only
to
those
serving
at
least
10,000
people.

6)
Disinfectant
Residual
Monitoring
and
Associated
Activities
under
the
SWTR
The
rule
allows
systems
serving
3,300
and
fewer
to
substitute
grab
sampling
for
continuous
disinfectant
residual
monitoring.
This
enables
small
systems
to
avoid
capital
costs
associated
with
continuous
monitoring
equipment.
Further,
the
number
of
daily
grab
samples
required
for
measuring
the
disinfectant
residual
is
directly
related
to
the
system's
size.
Systems
serving
500
or
fewer
people
are
required
to
take
one
sample,
while
systems
serving
2,501
to
3,300
people
are
required
to
take
four
samples.

7)
Arsenic
Rule
In
the
Arsenic
Rule,
in
order
to
assist
small
entities,
States
will
grant
monitoring
waivers
to
systems
that
are
reliably
and
consistently
below
the
MCL.
These
waivers
will
reduce
the
compliance
cost
for
some
small
systems
and
will
decrease
the
number
of
times
a
system
must
conduct
routine
monitoring.
In
addition,
the
monitoring
requirements
still
allows
systems
to
composite
up
to
five
samples.
Compositing
samples
allows
systems
to
reduce
the
laboratory
costs
associated
with
monitoring.

8)
Lead
and
Copper
Rule
In
developing
the
LCR
and
its
modifications,
EPA
considered
SBREFA
to
minimize
the
burden
of
information
collections
on
small
entities.
However,
while
preparing
the
LCRMR,
EPA
determined
that
the
LCR
would
not
have
a
significant
impact
on
a
substantial
number
of
small
entities.

EPA
recognizes
that
some
water
systems
are
small
entities;
therefore,
the
LCR
reduced
to
the
extent
practicable
and
appropriate
the
burden
on
PWSs,
especially
smaller
systems.
The
regulations
include
the
following
examples
of
reduced
burden
for
small
systems:


Different
compliance
or
reporting
requirements
or
schedules
that
take
into
account
the
resources
available
to
smaller
water
systems.


Consolidated
or
simplified
compliance
and
reporting
requirements.


No
unnecessary
or
redundant
requirements.

This

also
discusses
the
assumptions
used
to
estimate

and
costs
and
describes
the
change
in
annual
burden,
as
compared
with
the
2001
DDBP/
Chem/
Rads
Rules
ICR.
This
ICR
updates
the
annual
burdens
and
costs
associated
with
these
rulemakings
for
years
2005
through
2007.

EPA
is
committed
to
accurately
characterizing
the
burden
and
costs
of
rules
it
promulgates.
Consequently,
EPA
has
refined
some
of
the
assumptions
for
calculating
the
burden
and
costs
associated
with
implementing
the
drinking
water
regulations
contained
in
this
ICR.
For
this
update,
many
assumptions
were
revised
based
on
program
changes
and
well­
documented
changes
in
some
data.
To
provide
a
comparable
basis
on
which
to
calculate
the
requirements
addressed
by
the
DDBP/
Chem/
Rads
Rules
ICR
and
to
address
inconsistencies,
EPA
applied
uniform
assumptions
to
all
rules.
The
categories
of
assumptions
are
listed
below.

°
Labor
rates
 
for
PWSs,
a
mean
hourly
rate
of
$
17.09,
from
the
Bureau
of
Labor
Statistics
(
BLS),
with
an
overhead
rate
of
60
percent;
for
States,
the
hourly
rate
from
the
most
recent
State
Workload
Model.

The
annual
PWS
burden
for
years
2005
through
2007
is
estimated
to
be
approximately
4.30
million
hours.
Exhibit
7
(
at
the
end
of
Section
6(
b))
shows
the
annual
burden
hours
on
a
rulespecific
basis.
Wherever
possible,
activity­
level
burden
assumptions
were
carried
forward
from
previous
ICRs.
However,
if
updated
data
were
available
(
e.
g.,
system
inventories),
those
data
were
used
in
burden
calculations.
Appendices
B
through
H
show
the
assumptions
and
detailed
burden
calculations
for
each
rule.
The
following
further
describes
the
bases
for
the
burden
estimates
for
each
rule.

1)
Stage

Disinfectants
and
Disinfection
Byproducts
Rule
Activities
associated
with
the
Stage
1
DBPR
account
for
0.71
million
annual
burden
hours.
The
assumptions
used
to
calculate
the
Stage
1
DBPR
burden
are
based
largely
on
assumptions
from
the
September
1998
Information
Collection
Request
for
the
National
Primary
Drinking
Water
Regulations:
Stage
1
Disinfectants
and
Disinfection
Byproducts
Rule
(
Stage
1
DBPR
ICR).
The
burden
for
systems
includes
only
monitoring.
Based
on
the
rule's
implementation
schedule,
the
startup
burden
for
systems
was
included
in
prior
ICRs.
The
specific
burden
for
monitoring
includes
the
following
 

Paired
TTHM/
HAA5

Alkalinity
and
paired
TOC

Bromate

Chloride
Dioxide

Chlorite
(
both
daily
and
monthly
monitoring)


Chlorine
or
chloramines
(
in
the
distribution
system)
22
At
this
point,
reduced
monitoring
burden
was
not
estimated
for
the
above
contaminants,
with
the
exception
of
alkalinity
and
paired
TOC
monitoring,
which
carried
forward
reduced
monitoring

estimates
from
the
September
1998

Chemical
Phase
Rules
Activities
associated
with
the
Chemical

Rules
account
for
a
burden
of
0.45
million
hours
per

The
burden
estimate
includes
routine
and
reduced
sampling
for
IOCs,

under
the
schedules
dictated
by
the
SMF.
The
assumptions
used
to
calculate
the
Chemical
Phase
Rule
burden
are
based
on
assumptions
from
the
1993
PWSS
Program
ICR,
which
maintained
most
assumptions
and
burden
estimates
from
the
individual
ICRs
for
the
Phase

rules,
with
an
adjustment
to
the
waiver
rate
assumptions
(
in
the
2001
DDBP/

Rules
ICR)
to
more
accurately
reflect
actual

only.
The
startup

are
completed
and
the

has
now
dropped
out.
Activity­

1976
Radionuclides
Rule
and
2000
Radionuclides
Rule
For
this
ICR,
all
radionuclides
monitoring
will
be
addressed
by
the
2000
Radionuclides
requirements,
which
completely
absorb
and
augment
the
requirements
established
in
the1976
Rule.
Annual
PWS
burden
for
the
2000
Radionuclides
Rule
is
estimated
to
be
0.02
million
hours,
which
is
based
on
burden
assumptions
contained
in
the
2001
DDBP/

The
large
burden

Total
Trihalomethanes
Rule
For
this
ICR,
no
burden
is
calculated
for
the
TTHM
Rule
because
the
Stage

DBPR
completely
absorbs
the
TTHM
requirements
and
expands
them
to
address
systems
serving
fewer
than
10,000
people
and
NTNCWSs.

6)
Disinfectant
Residual
Monitoring
and
Associated
Activities
under
the
SWTR
As
stated
previously,
this
ICR
includes
burden
estimates
only
for
the
disinfection
residual
monitoring
and
associated
activities
required
under
the
SWTR.
The
Microbial

ICR
addresses
the
burden
and
costs
for
all
other
SWTR
requirements.
Implementation
of
the
SWTR
disinfection
residual

and
associated
activities
is
estimated
to
result
in
an
annual
PWS
burden
of
1.22

Included
in
the
estimate
is

Agencies
The
annual
burden
for
primacy
agencies
is
estimated
to
be
approximately
2.12
million
hours.
Exhibit

(
at
the
end
of
Section

shows
the
annual

on
a

basis.
Many
other
State
activities,
such
as
compliance
assurance
and
data
management,
cannot
be
divided
among
specific
rules
and
are
included
in
the
PWSS
Program
ICR
as
general
primacy
activities.
The
following
briefly
describes
the
bases
for
the
burden
estimates
 
1)
Stage

Disinfection
Byproducts
Rule
The
annual
State
burden
for
the
Stage
1
DBPR
is
expected
to
be
0.15
million
hours.
This
reflects
data
entry
and
recordkeeping
burden.
The
start­
up
activities
have
been
completed
and
have
been
taken
into
account
in
previous
ICRs.
Section

Detailed
calculations
for

2)
Chemical
Phase
Rules
For
States,
the
annual
burden
associated
with
the
Chemical
Phase
Rules
is
estimated
to
be
approximately
1.33
million
hours.
This
reflects
reporting
and
recordkeeping
burden
for
routine
and
reduced
sampling
for
IOCs,
VOCs,
and
SOCs
under
the
schedules
dictated
by
the
SMF.
Estimates
for
primacy
agency
burden
for
the
Chemical
Phase
Rules
are
based
on
State
Workload
Model
Assumptions
carried
forward
from
the
1993
PWSS
Program
ICR.
Because
it
is
now
a
part
of
the
Arsenic
Rule
burden,
an
estimate
of
the
burden
hours
associated
with
arsenic
monitoring
has
been

includes
activities
such
as
coordinating
with
EPA,
providing
data
management
support,
and
assisting
in
the
implementation
of
the
program.
In
addition,
the
burden
includes
overhead
costs
for
support
staff
related
to
rule­
specific
training
and

1976
Radionuclides
Rule
and
2000
Radionuclides
Rule
For
the
1976
Radionuclides
Rule,
there
is
no
annual
State
burden
because
the
cost
and
burden
are
now
completely
represented
by
the
2000
Radionuclides
Rule.
For
the
2000
Radionuclides
Rule,
annual
State
burden
is
estimated
to
be
0.002
million
hours.
The
annual
State
burden
is
based
on
burden
assumptions
contained
in
the
2001
DDBP/
Chem/
Rads
Rules
ICR.
Burden
is
calculated
for
primacy
agency
staff
for
monitoring
activities
only
because
start­
up
activities
have
been
completed
(
i.
e.,
there
is
no
burden
or
cost
for
these
activities).
Monitoring
burden
is
derived
based
on
recordkeeping,
reporting,
and
compliance
tracking
and
analysis
requirements
for
analyses
conducted
by
PWSs.
Section

SWTR
As
stated
previously,
this
ICR
includes
burden
estimates
for
only
the
disinfection
residual
monitoring
and
associated
activity
components
of
the
SWTR.
The
Microbial
Rules
ICR
addresses
the
burden
and
costs
for
the
other
SWTR
requirements.
Implementation
of
the
SWTR
disinfection
residual
monitoring
is
expected
to
result
in
an
annual
State

of
0.33
million
hours.

Arsenic
Rule
For
the
2001
Arsenic
Rule,
annual
State
burden
is
estimated
to
be
0.09
million
hours.
The
annual
State
burden
is
based
on
assumptions
contained
in
the
2000
Arsenic
Rule
ICR.
Burden
is
calculated
for
primacy
agency
staff
for
monitoring
activities
only.
Since
the
start­
up
activities
have
been
completed,
no
burden
or
cost
is
reported
for
these
activities.
Monitoring
burden
is
derived
based
on
recordkeeping,
reporting,
and
compliance
tracking
and
analysis.
Section
6(

describes
the
reasons
for
changes
between
the
burden
reported
in
the
2000
Arsenic
Rule
ICR
and
this
ICR.
Calculations
for
cost

Lead
and
Copper
Rule
EPA
estimates
that
the
annual
burden
incurred
by
primacy
agencies
for
activities
associated
with
the
lead
and
copper
regulation
is
approximately
0.21
million
hours.
This
estimate
includes
costs
for
employing
a
corrosion
control
expert
and
costs
to
review
various
letters
and
results
submitted
by
water
systems
in
accordance
with
the
LCR.
Further
detail
about
these
activities
and

Exhibit

shows
the
annual
costs
for
PWSs
over
the
three­
year
ICR
period.
Annual
costs
are
estimated
at
approximately
$
312.4
million,
which
consists
of
$
187.8
million
in
O&
M
costs,
$
6.9
million
in
capital
costs,
and
$
117.7
million
in
labor
costs.

Labor
costs
are
based
on
the
number
of
burden
hours
times
the
average
hourly
wage
rate,
including
overhead.
The
average
hourly
wage
rate
is
the
rate
quoted
by
the
Bureau
of
Labor
Statistics
(
BLS)
for
Standard
Occupational
Classification
(
SOC)
Code
51­
8031,
"
Local
Government
 
Water
and
Liquid
Waste
Treatment
Plant
and
System
Operators."
The
quoted
rate
was
$
16.64
in
2002
dollars
(
see
http://
stats.
bls.
gov).
For
consistency,
this
rate
has
been
inflated
to
2003
dollars
using
the
Employment
Cost
Index.
The
inflated
rate
is
$
17.09.
In
addition,
60
percent
overhead
was
assumed,
bringing
the
loaded
rate
to
$
27.34
in
2003
dollars.

In
addition
to
labor
costs,
there
are
O&
M
costs
associated
with
the
each
of
the
rules
covered
by
this
ICR.
These
O&
M
costs
reflect
non­
labor
costs

each
of
the
rules.
These
costs
vary
by
rule
according
to
the
frequency
and
cost
of
a
particular
analysis.

In
addition
to
O&
M
costs,
the
requirements
of
one
rule
(
i.
e.,
SWTR)
result
in
capital
costs
to
affected
PWSs.
Capital
costs
are
incurred
to
buy
and
replace
monitoring
equipment
necessary
for
on­
site
analysis
of
disinfectant
residuals
and
water
pH.
Capital
costs
are
based
on
vendor
estimates
for
both
in­
line
and
portable
equipment,
as
required
by
regulations.
Equipment
costs
are
based
on
a
seven­
year
replacement
cycle.
Details
on
both
the
capital
and
O&
M
costs
associated
with
each
rule
can
be
found
in
Appendices
B
through

Cost
to
Primacy
Agencies
Exhibit
8
shows
that
the
annual
cost
to
primacy
agencies
is
estimated
at
approximately
$
67.4
million,
which
is
comprised
almost
exclusively
of
labor
costs.
There
are
some
O&
M
costs
associated
with
the
Lead
and
Copper
Rule
($
0.005
million).
The
labor
costs
are
based
on
an
average
full
time
equivalent
(
FTE)
cost
of
$
66,008
including
overhead,
which
equates
to
approximately
$
31.73
per
hour.
23
This
rate,
which
has
been
inflated
to
year
2003
dollars,
is
based
on
the
rate
($
55,000)
suggested
by
the
workgroup
that
developed
the
State
Workload
Model
in
1997.
There
are
no
primacy
agency
capital
costs
associated
with
this
ICR.

Estimating
Respondent
Universe
and
Total
Burden
and
Costs
Respondents
for
this
ICR
include
both
PWSs
and
States
or
other
primacy
agencies.
This
ICR
estimates
that
the
number
of
PWS
respondents
is
161,217
existing
PWSs.
25
However,
all
PWSs
are
not
necessarily
subject
to
each
of
the
information
collection
requirements
contained
in
this
ICR.
The
regulations
associated
with
each
rule
identify
the
numbers
and
types
of
PWSs
that
are
subject
to
each
particular
provision.
In
addition
to
the
PWS
respondents,
this
ICR
assumes
57
primacy
agencies
(
50
States
plus
D.
C.,
U.
S.

and
the
Navajo

26
Therefore,
the
total

presents
the
change
in

and
explains
the
reasons
for
the
change
in
burden.
The
discussion
is
divided
into
two
parts
 

Section

the
restructuring

being
made
for
the

These

are

Burden
associated
with
the
Arsenic
Rule.
The
total
annual
respondent
burden
estimated
in
the
Arsenic
Rule
ICR
was
approximately
0.667
million
hours
per
year.
The
total
annual
respondent
cost
estimated
in
the
Arsenic
Rule
ICR
was
approximately
$
12
million.
The
annual
respondent
burden
included
approximately
0.616
million
annual
hours
for
PWSs
and
0.051
million
annual
hours
for
primacy
agencies.
The
annual
respondent
cost
included
approximately
$
10.4
million
for
PWSs
and
$
1.6
million
for
primacy
agencies.
There
were
no
EPA
costs
or
burden
associated
specifically
with
the
Arsenic
Rule.
In
order
to
consolidate
DDBP/
Chem/
Rads
rules,
EPA
is
requesting
that
these
hours
be
moved
to
the
DDBP/

(

Other
Burden
Adjustments
Changes
in
calculated
burden
are
a
result
of
updating
relevant
baseline
information
for
each
rule
with
the
most
current
and
accurate
information
available
(
e.
g.,
PWS
inventories).
Where
appropriate,
estimated
violation,
waiver,
and
other
associated
rates
have
also
been
updated
to
reflect
current
information
on
rule
compliance.
Exhibits

and

summarize
reasons
for
these
changes
and
quantify
the
changes
by
rule.
Burden
adjustments
associated
with

resulted
in
a
burden
decrease
of
0.40

and
are
detailed
in

for
the
period
covered
by
this
ICR.
Most

For
monitoring
activities
that

Therefore,
in

Burden
Statement
The
public
reporting
burden
for
collections
included
in
this
ICR
is
detailed
in
Exhibit
14
above.
The
annual
respondent
burden
is
estimated
to
average
approximately
6.4
million
hours,
of
which
4.3
million
hours
are
attributable
to
PWSs
and
2.1
million
hours
to
primacy
agencies.
These
estimates
include
time
for
gathering
information
as
well
as
developing
and
maintaining
records.

Burden
means
the
total
time,
effort,
or
financial
resources
expended
by
people
to
generate,
maintain,
retain,
disclose,
or
provide
information
to
or
for
a
Federal
agency.
This
includes
the
time
needed
to
review
instructions;
develop,
acquire,
install,
and
utilize
technology,
and
systems
for
the
purposes
of
collecting,
validating,
and
verifying
information,
processing
and
maintaining
information,
and
disclosing
and
providing
information;
adjust
the
existing
ways
to
comply
with
any
previously
applicable
instructions
and
requirements;
train
personnel
to
be
able
to

to
a
collection
of
information;
search
data
sources;
complete
and
review
the
collection
of
information;
and
transmit
or
otherwise
disclose
the
information.
An
agency
may
not
conduct
or

and
a
person
is
not
required
to
respond
to,
a
request
for
information
collection
